Unexplained “Phoenix Lights” explosion caught live on news broadcast

Phoenix's FOX 10 reporter Andrea Robinson was in the middle of an on-air report when an unexplained, bright white explosion appeared in the distance behind her.

The strange blast was caught on tape and aired live during Robinson's report. At first, news station employees thought the explosion was a transformer. But when FOX 10 checked with local utility providers APS and Salt River Project, they were told no transformers had blown in the area.

Arizona is also home to Travis Walton, who famously claimed to have been abducted by a UFO in 1975. Walton has written a number of books on the subject, and his story was turned into the 1993 film "Fire in the Sky."

And while Phoenix officials remain stumped by the strange light explosion, FOX 10 has reached out to the public asking for assistance in explaining exactly what was caught on film.
